Version 1.00 of the Accel64 for Linux software builds loadable kernel module (LKM) software for the GNU/Linux system for running on 32- or 64-bit hardware architectures. It supports control of DAP data acquisition boards on systems using kernel versions in the 4.xx series. The software determines what kind of hardware platform is present and selects the native interface mode as the default. However, advanced users who have implemented kernel support for 32-bit software architectures under a 64-bit hardware platform can use either the 64- or 32-bit interface, depending on application requirements.
